It felt like I was supposed to be able to fight in the arena, now everyone is gone and the last time I was there, no one allowed me to enter some fight.

I don't know if the car it's supposed to go trough the non car-friendly areas. For me it goes right trough and that made my car get stucked inside the snowy zone where I can't get into because it sends me to the location. As going walking all around the map is not the intended gameplay (and really slow) I hope that at some point it just tp to my last location or something, if it does I'll inform here....

I finished the satellite ending two times but the achiv doesn't see to work

So, I've met this boss and managed to kill it with poison from Occidere, which was as overpowered as I knew it from other RPG maker games, and truth be told, without it I wouldn't stood a chance. But as far as I know I should have gotten an achievement for that fight, what didn't happen. Okay, so I gave it another try. But in any subsequent approach the poison dealt only like 400 instead of 6000+ damage. Was it bugged in my first run? Or is it bugged later? Or am I missing a mechanism? Some feedback regar...

I managed to get all other achievements except this on even tho I defeated Vurrus multiple times now.
